Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Buffer overflow in wconsole.dll in Rockliffe MailSite Management Agent allows remote attackers to execute arbitrary commands via a long query_string parameter in the HTTP GET request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A buffer overflow vulnerability exists in wconsole.dll, a component of Rockliffe MailSite Management Agent. By sending an HTTP GET request with an excessively long query_string parameter, remote attackers can overflow a buffer and execute arbitrary commands on the affected system with the privileges of the vulnerable service.

MitigationApply available patches from the vendor. If patches are unavailable due to end-of-life status, decommission or isolate the affected system and migrate to a supported mail server management solution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Rockliffe MailSite is installed
    Check for MailSite installation directories (typically under C:\Program Files\Rockliffe or similar), or query the Windows registry under HKLM\SOFTWARE\Rockliffe for product information
    Affected if Rockliffe MailSite is found on the system
  2. Determine the installed version of Rockliffe MailSite
    Check the version information of the MailSite executable or DLL files, or query the registry key HKLM\SOFTWARE\Rockliffe\MailSite\Version
    Affected if The installed version is 4.2.10
  3. Verify if the Management Agent component (wconsole.dll) is present
    Search for wconsole.dll in the MailSite installation directory, typically in a bin or management subfolder
    Affected if wconsole.dll exists in the MailSite installation path
  4. Determine if the Management Agent service is exposed to network
    Check if the Management Agent HTTP service is running and bound to a network interface (typically TCP port 9999). Use netstat -an | findstr 9999 or review service configuration
    Affected if The Management Agent HTTP service is listening on a network-accessible port

A system is affected if Rockliffe MailSite version 4.2.10 is installed with the Management Agent (wconsole.dll) component exposed over the network.
